Title: Wave shed loom weft winder - with two units to hold and control spool winder with shock-free action (CS 29.6.79)
Inventor: GALPERIN ALEKSANDR L
IPC: D03D47/26
Filed: 1978-10-11
Abstract: To wind the weft yarn on to a spool on a carrier, for use in a wave shed loom, there is a prim. unit to hold the winding components in a predetermined posn. after the satellite wheels and rack have been disengaged. A fixable quadrant is mounted diametrically opposite the rack, with projections attached to the satellite wheels to act on the periphery of the quadrant when moved against it by the disc. A sec. unit consistently releases and stops the winding unit in a preset posn., with two cams to give a shock-free release and stop action. This is placed above the overlaping sections of the satellite wheels running at any time from the quadrant to the rack and from the rack to the quadrant. One of the number of winding units has a corresponding number of paired studs of which each pair is attached to a satellite wheel. One stud of the pair acts with the release cam while the other stud acts with the stop cam. Design increases the capacity of a wave shed loom and simultaneously reduces weft yarn wastage.

Title: Fluidised bed cooler - for gases from coal gasification, also removes dust and tar
Inventor: KYDD PAUL H DR
IPC: B01D46/38
Filed: 1980-07-24
Abstract: Process and appts. are claimed for the cooling and removal of dust particles and tar from the hot effluent gas from a coal gasifier, esp. a rapid fluidised bed gasifier. The appts. has a fluidised bed of coke and ash particles, contg. a member of tubes, through which a coolant liq. flows. The tars condense, the fire dust particles agglomerate, and excess coke particles are continuously returned to the gasifier. The fluidised bed cooler may be preceded by a cyclone for the removal of coarse particles. Used in association with gasification of anthracite and coals (bituminous or sub-bituminous). Avoids the problems of direct water cooling, i.e. a large water usage, contaminated water prod. and difficulty of recovering latent heat are avoided. Rapid fluidised bed gasifier can advantageously be coupled to a rapid fluidised bed cooler, because both will have a large capacity for flow- and load-variation.

Title: Apparatus for the conveyance of coal in systematic underground mining operations
Inventor: PAURAT FRIEDRICH WILHELM
IPC: B65G15/44
Filed: 1981-01-24
Abstract: The invention proceeds from an apparatus for the conveyance of coal and similar conveyed material in systematic underground mining operations. It relates, in particular, to a longwall conveying apparatus. In its basic construction, the apparatus consists of a conveying trough with a conveying-trough bottom and conveying-trough sidewalls, a conveyed-material mover and a drive device. The conveyed material and the conveyed-material mover slide over the conveying-trough bottom. The conveyed-material mover is guided in rotation with a forward strand and return strand via a deflecting device and is driven by at least one toothed driving roller of the drive device. In order to avoid a conveyed-material mover with heavy traction ropes and scrapers and the associated friction of steel on steel, the conveyed-material mover is designed as a conveying net. This has pull-transmitting net strings, net-string connecting elements and conveying-net meshes allowing a penetration and/or passage of fractions of conveyed material. The conveying-net meshes engage, at least in the edge region of the conveying net, with the toothed driving roller. This reduces the friction between the conveyed-material movers and conveying trough and the like. In addition, the conveying-trough bottom and/or the conveying-trough sidewalls, including possible guide channels, can be provided with a friction-reducing coating. This can be an ice layer which is produced via special icing devices.
